A hyperextended finger injury occurs when the ligaments on the palm side of your fingers stretch or slightly tear, causing a sprain to those ligaments. Ligaments are connective tissues that hold two bones together at a joint. Treatment for a hyperextended finger is ice, immobilization, rest, and anti-inflammatory medicine. Strengthening exercises should start as soon as swelling and pain has decreased.

Muscle and connective tissue injuries include sprains and strains, which are the most common injuries for people engaged in physical sports. A sprain is an injury of a ligament, which connects our bones to each other. A strain is an injury that can occur to a muscle or a tendon, which connects our bones to our muscles. If you have a muscle or connective tissue injury, you will likely experience pain, swelling, and limited movement of that body part. Sometimes these injuries are evident as soon as they occur, while others take time to develop. Usually rest helps to heal the area, and ice can reduce swelling. If these remedies dont help you, physical therapy or surgery may be necessary for a full recovery.
